Opal and POWER9 DD2

Patch sent to kernel-team mailing list: https://lists.ubuntu.com/archives/kernel-team/2017-July/085402.html

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I am not able to test this bug on DD2 hardware at this moment, but I tested on DD1 and POWER8 and I didn't see a regression. Marking it as validated.
